Problems solved by technology

Changes in air pressure will cause a pressure difference between the inside and outside of the insulating glass, causing the glass to deform, or the edge sealing material to crack and shorten the life, or even break the glass
For example, the existing locomotives operate on the Qinghai-Tibet Railway with a maximum altitude of 5,072 meters. The external air pressure at this altitude is only 0.5 atmospheres, forming a pressure difference between the inside and outside air. If the p

Abstract

A hollow glass assembly capable of automatically adjusting air pressure comprises an outer layer plate and an inner layer plate. The outer layer plate and the inner layer plate are fixedly connected through fixing frames and form a hollow cavity. The fixing frames and the outer layer plate are in airtight connection. One or more through holes are formed in the fixing frames. The hollow cavity is provided with a sealing plate and one or more elastic connecting devices which can deform; the sealing plate is in airtight connection with the outer layer plate or the fixing frames through the elastic connecting devices to form an airtight cavity with the volume being changeable; and a communicating cavity, except the airtight cavity, in the hollow cavity communicates with outside air through the through holes. A hollow glass window capable of automatically adjusting the air pressure can adapt to the problem of internal and external pressure difference, faced by hollow glass, caused by elevation change in the railway train running process, the weight of the glass is reduced as much as possible, energy is saved, consumption is reduced, and the service life can reach 20-30 years.

Description

technical field [0001] The invention relates to a hollow glass assembly with automatic air pressure adjustment, which can be used for EMUs, locomotives, aircrafts, especially the doors and windows of vehicles running on lines with changing air pressure, which have requirements for heat insulation, sound insulation, strength and weight reduction. Background technique [0002] For windows of locomotives or EMUs operating between different altitudes, composite insulating glass is basically used due to their special requirements for heat insulation, sound insulation, weight and perspective. The insulating glass is a rigid sealing body, and the external air pressure will also change when the altitude of the operating line changes. Changes in air pressure will cause a pressure difference between the inside and the outside of the insulating glass, causing the glass to deform, or the edge sealing material to crack and shorten the life, or even the glass to break. For example, the e...
